Update: I have acquired some additional equipment for coin photography. But I haven't had the time to play around with them. Over Christmas I'll be able to take some pictures.
I picked up a copy stand with two lights. Nothing elaborate or expensive ($40), but it will do its job. I picked this up after reading several members touting the benefits over a tripod.
But the jewel I just received is an Olympus M.Zuiko 60MM f2.8 Macro lens. It's a true macro lens! After taking a few test shots, I can tell it is superior over the macro adapter for the 12-42MM lens or using the macro art setting.
I will be using the same coins in my previous posts to show the progression of technology I have used for my Olympus camera since the original post.
Pictures posted soon :)
